Diastereoselective Synthesis of Cyclic sp3-Enriched cis-β-Alkoxysulfonyl Chlorides

A three-step synthesis of β-alkoxy-substituted alicyclic sulfonyl chlorides from cyclic alkenes and alcohols is reported. The scope of the method was studied for a range of the substrates with various steric and electronic properties. The title compounds were obtained on a hundred-gram scale in up to 52% overall yield scale as single cis-diastereomers.
